In Fig. 4 I have illustrated one means whereby an undue supply of water is prevented when the lamp is subjected to severe concussion, as is frequently the case in use upon a bicycle. This end I accomplish by the addition of a gauze filling K between the valve E and the water-supply tube D. The presence of this filling K will not prevent the descent of the water; but in the event of concussion it will offer a resistance to the quick passage downwardly of said liquid, and in experience I have found it to be one satisfactory means for accomplishing the desired end.

What I claim is- 1. In an acetylene-gas lamp, a water-chamber, a gas-generating chamber, a water-supply pipe depending directly from said waterchamber, an elongated valve controlling an opening in said water-supply pipe, a valveseat in said opening adjustably mounted in line with said valve, and a water-distributing pipe around said valve and valve-seat and within said generating-chamber.

2. In an acetylene-gas lamp, a water-chamber, a gas-generating chamber, a water-supply pipe, a valve controlling an opening in said supply pipe, a valve seat adjustably mounted with respect to said opening, and in line with said valve, and a slitted Water-distributing pipe around said valve and valveseat and within said generating-chamber.

3. In an acetylene-gas lamp, a water-chamber, a gas-generating chamber, said chamber being made up of a plurality of sections, a water-distributing pipe carried by one of said sections, a water-supply pipe projecting into said distributing-pipe and connected with the Water-chamber, an outlet in said supply-pipe, a valve for controlling said outlet and a valveseat to cooperate with said valve.

4. In an acetylenegas lamp, a water-ch amber, a gas-generating chamber, the casing for which is formed in sections, a Water-distributing pipe having slots in its side, said pipe being bulged adjacent said slots and means to feed water from the water-chamber into said distributing-pipe.

5. In an acetylene-gas lamp, a water-chamber, a gas-generating chamber, the casing for the latter being separable, a distributing-pipe having openings in the sides thereof projecting into said generating-chamber, a Watersupply pipe projecting into said distributingpipe and means for controlling said watersupply comprising a longitudinally-adjustable valve and a controlling-handle therefor attached directly to said valve, and a graduated holding-rack for said controlling-handle.

6. In an acetylene-gas lamp, a gas-generating chamber and a distributing-pipe projecting into said chamber, said distributingpipe being provided with slots and being bulged adjacent said slots, in combination with a Water-supply and means for regulating the same.
